yLetters Patent A' 106,468, dated Ang/ust 16, 1870.

' I MPRQVMENT 1N BLOCKS FoR CARPET-PRINTING.

The Schedule' referred to n-these Letters Patent and making part of the same Figure l is a -planyiewofa 'sheet of metal, as it appears after having beenprepared for the reception of the pegs or types, showing also a portion of such types in position. l

Figure 2 is a vertical sectional elevation, showing the types in position upon therplate, and the plate .as

secured to a block of wood or other material.

Blocks for printing carpets and other fabrics have heretofore been constructed of wood, gutta-percha, and metal, with the gures which they were intended to print engraved or otherwise. formed upon their lower surface.

lhey have also been formed by preparing blocks-'of'. metal with surfaces as large as the figure to be printed, and then, by means of machines constructed for the purpose, drilling holes in one face of such blocks for the reception of the types, into which` a round projection upon the upper ends of such types was driven. lhose made of metall have' sometimes been electrotyped, as set forthin a patent-granted to me on the 1st day of November, 1859.

All of the above-referred-to blocks have been found to be objectionable: The wooden ones from the fact that larger lines would invariably be madev upon the fabric than was intended, or lines larger than the surface which was presented to such fabrics; lthe guttapercha ones from the fact that great dilicnlty was experienced in forming them with the perpendicular sides, so necessary to enable them to penetrate the fabric for a distance suicient to carry the colors to the proper dept-l1 therein; the eleetrotyped metallic ones-which have been found to be greatly superior to all that had preceded themfromtheir great cost, and the length of time requiredin their preparation; those consisting of blocks of metal with holes drilled i'n them for the reception of the pegs or types, because ot' their great cost, it requiring expensive machinery for drillingr such holes the weight of the block being also objectionable, especially in hand printing.

My object in the present invention is to provide a simple, cheap, and durable block, which shall be free from all the objections urged against previous ones; and t-o this end It consists in constructing a block for. printing carpetsand other fabrics, by the use of a sheet of any suitable metal, having perforations in it, orindeutations in one of its surfaces forthe reception of t-he types or pegs while to its opposite vsurface is attached a backing of wood, gutta-percha, or any other suita- Vble substance, as will be more fully described bereinafter.

A, in the drawing, representsV a sheet of metal, which is to be of suitable thickness to admit of the types being soldered to it, and which, for convenience, it is proposed to lay or mark off into squares, as shown in g. l. In the center of each of these squares, or so many of them as is necessary, there is vto be formed a small hole or indentation, for the reception ot" the end of the peg or type, or of a tenon or rounded projection formed thereon. \Vhen the plate is provided with apertures which extend all of the way through it, the types should be provided `with the projectionsV above alluded to but when it is provided with indentations only, as shown in fig. 2, vthe ends of the types may be made to rest in such indentations, and thereduced portion projectingt-herefrom may be dispensed with.

This portion of the device' may consist of a sheet of any kind of metal to which typescan he soldered, audit may bc prepared for the reception of such types, either by being drilled or punched; but, when indented only, it may, receive all of the impressions from abloc'k or stamp prepared expressly for that purpose. A

Then the sheet of metal has been prepared for the reception of the types C, they are to be inserted into so many of the holes or indentations as are necessary to produce the figure which it `is desirable to print. When the position ofthe types has been determined,

and they have been placed therein, they are soldered.V

fast to the plate, which will give thel outline of thev figure, after'which any portions of the spaces between such types may be filled with solder or other met-al,

so as to cover as large a space upon the fabric as is desirable; or such spaces may be tilled with leather, gutta-percha, or other elastic substances..

B represents the backing of wood, gntta-percha, or other suitable material, upon which the plate A is to be fastened in any suitable manner.

O C represent the pegs or types, they being shown in iig. 2, as inserted into indentations formed in the plate A. It will be apparent that, aftcnthey have been secured as there indicated, the spaces between them may be lilled with any suitable subst-ance which will give them permancncy, and that this filling may extend for any desired dist-ance from the point where they are united to the plate toward their outer ends.

a t represent the indentations for the reception ot' the types. e

The operation 'of this device will be apparent.

1t having been constructed as above described, itis to be attached to a printing-machine, or taken in the hands ot theoperator and placed upon the inking or coloring-form, in order that the ends of the types may be covered with such matter, aft-er which it is to be removed to the position where the figure is to be printed, when it is to be lowered upon the fabric and pressed down' thereon, either by its own weight or by some other means, until the coloring matter has been transferred to such fabric, where it will leave its irnpression, after which it is to hcxcarried back to the coloring-form for a fresh supply. y

I have described this device as'particularly adapted to the printing'of carpets, but it is equally adapted to the. printing ot' other fabrics.

I am aware that blocks for the purpose to which I propose to apply mine have heretofore been made, consisting of plates of metal having perforations for the\ends ot' the types, and also,l that various substances have been used as backing for blocks and for. the same purpose, I do not, therefore, claim either of the devicesnamed in this specification respectively. or dually; but

Having thus described my invention, What I claim, and desire to secure by Letters P at- A block for printing carpets and other fabrics, coinbining n its construction a sheet of metal, which is provided with perlbratious or indentations for the re ception of the types, a'hacking of wood,'or other equivalent substance, to which the plate is attached, and the types or pegs for giving the impression, suhstantially as and for the purpose set forth.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses. v
